I am a 62-year-old male with ibs-c and reflux. Every 6months or so I get bouts of stomach burning, bloating and nausea directly after eating. The last time I became constipated as well. Over a period of 6 weeks I increased my dosage of acacia tummy fiber until I was using 5 heaping Tbs per day. The reflux subsided, the stomach symptoms calmed down too. But the constipation remained. In the end I was forced to give up on this product in order to successfully address my constipation issue.
